Properly fixed Adaptec AHA-1640 MCA adapter, setup is handled directly by the ADF file in the reference disks.

Re-introduced the Acer V35n machine, but with a proper bios (r01-c0.bin instead of the service one).
MCA serial and parallel initialization fixes alongside the ISA PS/1 and PS/2 Model 30 ones.
